I consider fieldwork the best way to get reliable data for linguistic analysis, and I have developed a number of not-so-traditional ways of collecting information and data. For instance, I produced the film "A strawberry-shaped day" as a Nordic alternative to Wallace Chafe's famous Pear film. The Strawberry film has then been used as a prompt and stimulus in order to get narrative and interactive data.

Over the years, I have organized and been involved in several fieldwork expeditions, primarily in Swedish-language Finland. I was also a member of the steering committee of the large-scale data-gathering endeavor Spara det finlandssvenska talet that the Society of Swedish literature in Finland (SLS) financed 2005-2008, resulting in interviews and discussions with some 1,000 (dialect) speakers of Swedish in Finland.

Varieties: immigrants' varieties, esp. in the Närpes and Pedersöre areas
